Opto ramp switch board


New design of the 3 opto PCB (also referred to as a ramp opto board) used on many Williams WPC pinball machines.

The new design has a number of improvement from the factory original:

  • Status LEDs give full diagnostics of each transmitter and receiver!
  • Lower current consumption and less heat, for longer life.
  • User serviceable with transistors that are replaceable with thru-hole equivalents.

This opto ramp switch board assembly is a substitute for the following part numbers:


  • A-13901
  • A-17042
